dc.description.abstract | We investigated environmental impact of large-scale dyke on the sediment geochemistry, sulfate reduction rates (SRRs), sediment oxygen demand (SOD) and potential contribution of benthic nutrient flux (BNF) to primary production in the Yeongsan River estuary, Yellow Sea. The sediment near the dyke (YE1) with high organic carbon (C-org) content ( ˃ 4%, dry wt.) was characterized by extremely high SOD (327 mmol m(-2) d(-1)) and SRRs (91-140 mmol m(-2) d(-1)). The sulfate reduction accounted for 73% of C-org oxidation, and was responsible for strikingly high concentrations of NH4+ (7.7 mM), PO43- (67 mu M) and HS- (487 mu M) in pore water. The BNF at YE1 accounted for approximately 200% of N and P required for primary production in the water column. The results present one of the most extreme cases that the construction of an artificial dyke may have profound impacts on the biogeochemical and ecological processes in coastal ecosystems. | en_US |
dc.description.sponsorship | This research was supported by a Korean Long-term Marine Ecosystem Research (K-LTMER) program titled "Long-Term Change of Structure and Function in Marine Ecosystem of Korea" and "Gyeonggi Sea Grant Program" funded by the Korean Ministry of Ocean and Fisheries, and partly by the Korea Institute of Ocean Science and Technology (KIOST; PE99532 and PE99513). The authors thank two anonymous reviewers and Prof. Paul Shin (handling editor) for their comments that improved the earlier version of the manuscript. | en_US |
